It turns out Google Chrome (via Chromium) includes a default extension which makes extra services available to code running on the `*.google.com` domains - tweeted about today [by Luca Casonato](https://twitter.com/lcasdev/status/1810696257137959018), …
Simply noone ever looked and it’s not documented. And the api is locked to work only on google domains so it wasn’t usable to anyone to accidentally notice what’s going on.

This is interesting because it is a clear violation of the idea that browser vendors should not give preference to their websites over anyone elses.
Follow up question: How many other parts of the chromium codebase limited to work on (maybe other) specific domains?
Isn’t chromium open source? How are the APIs a secret?
